History
of X-Men Reprint Issues (X-Men #67-93)

The X-Men comic franchise
began in 1963 with the publication of X-Men #1, featuring the
teen-aged mutants Cyclops, Beast, Angel, Iceman, and Marvel Girl,
mentored by the wheelchair-bound Professor X. The series produced
original stories though issue #66 (published in March of 1970), but,
with the publication of X-Men #67 (December, 1970), these comic books
featured reprinted stories from past X-Men comics. For instance,
X-Men #67 contained the story first printed in X-Men #12, and did not
feature any new or original stories.

This "X-Men Reprint Era"
continued on until the first new story in the regular X-Men series
with X-Men #94 in August of 1975. X-Men #94 featured the new X-Men
team first introduced in Giant-Sized X-Men #1, which came out in May,
1975. That large and historic issue brought together a new team of
X-Men assembled by Cyclops and Professor X to rescue the old team.
These new X-Men included Wolverine, Storm, Nightcrawler, Banshee,
Thunderbird, and Sunfire, who continued on as the main X-Men team in
X-Men #94, and beyond.
